Embodiment Construction

[0047] The present invention will now be described more fully with reference to the accompanying drawings, which show preferred embodiments of an authentication device and an authentication method in a wireless mesh network according to the present invention.

[0048] Figure 1 is a conceptual illustration of a public wireless mesh network.

[0049] As shown in FIG. 1 , the nodes of the wireless mesh network 20 are generally divided into mesh nodes 21-1, 21-2, 21-3, etc. that constitute the wireless mesh network 20, and mesh nodes 21-1, 21-2, 21-3, etc. 50 or another mesh network) to connect to the master node 22 as a gateway.

[0050] The grid nodes 21-1, 21-2, 21-3, etc. can be connected together in a multi-hop grid structure, and the master node 22 can be connected with an authentication server (AS) for The nodes 21 - 1 , 21 - 2 , 21 - 3 , etc. are authenticated when they enter the wireless mesh network 20 .

[0051] For the mesh nodes 21-1, 21-2, 21-3, etc. - 1, 21-2, 21...

Abstract

In an authentication apparatus and an authentication method for nodes in a wireless mesh network, an authentication server performs an initial authentication process for a new node entering the wireless mesh network, and a hop-by-hop authentication process between the new node and an adjacent node is performed between the new and adjacent nodes, based upon authentication information provided from the server. As a result, the server need not be involved in the hop-by-hop authentication process. Also, the initial authentication process for the new node is performed quickly, and the problem of hop-by-hop authentication associated with authentication information sharing is overcome. Furthermore, it is possible to prevent any malicious node from entering the wireless mesh network.

Description

technical field [0001] The invention relates to an authentication device and an authentication method in a wireless grid network. Background technique [0002] In order to adapt to the development of network technology and users' demand for better service quality, wireless network has won more attention until today. [0003] In wireless networks, due to the increasing demand for integrating ad hoc networks with existing networks, there will be a rapid expansion of distributed wireless mesh networks. [0004] In this wireless mesh network, multiple nodes are wirelessly connected in a mesh-like structure. [0005] Nodes of a wireless mesh network are generally divided into mesh nodes constituting a network and a master node connected to a different network (eg, a wireless network or another mesh network) to serve as a gateway. [0006] Mesh nodes can be connected together in a multi-hop mesh structure, and master nodes can be connected with authentication servers (AS) that a...
